Title: Frequency modulation method and device
Inventor: MARUTEIN BINTERAA
IPC: H01L27/12
Filed: 1990-11-19
Abstract: PURPOSE: To block generation of alias signals by separating a modulation signal into low and high frequency components through different methods and then modulating two signal components respectively. CONSTITUTION: Output from an adder A1 is multiplied by a coefficient Δf/fs through a coefficient element K3 and the output therefrom is fed, on one hand, to the input of a first integrator I1 and, on the other hand, to the input of a second integrator I2. Output from each integrator is multiplied by 2π through a coefficient element K2. A signal incoming from the first integrator 11 is then fed to a sine table SIN and a signal incoming from the second integrator I2 is then fed to a cosine table COS. Output from a subtrator S is multiplied by 2πΔf/f through a coefficient element K4 and fed to the input of a third integrator I3. Outputs from the cosine table COS and the third integrator I3 are fed, respectively, to two inputs of a multiplier M.  Outputs from the multiplier M and the sine table SIN are fed, respectively, to two inputs of a third adder A3 having an output representative of output from an FM modulator.

Abstract: PURPOSE:To design the title method so that an arrangement state of a reinforcing fiber is not restricted by an aspect ratio or a fiber length by dispersing and arranging the reinforcing fiber uniformly, by a method wherein a through hole is bored into a fiber mat where the fiber has got entangled so that the fiber becomes kinked irregularly in a three-dimensional direction and after a funnel-like puring port has been pierced through the bottom of the inside of the said through hole, a hydraulic composition is fed within the fiber mat by filling the same into the fiber mat while vibrating a bucket. CONSTITUTION:A through hole 3 is bored into a fiber mat 2 formed by entangling the same in a carbon long fiber 1 so that the carbon long fiber 1 becomes kinked and the mat 2 is held into a form 4. When a vibrator 10 is operated by loading hydraulic composition slurry 5 within a bucket 7 formed by sagging a funnel-like pouring port 6 corresponding to a position of the through hole 3, bucket supporting metal fittings 11 are vibrated and the slurry 5 of the bucket 7 flows to the fiber mat 2 through the pouring port 6 while rocking the bucket 7. Then the slurry 5 is filled into the fiber mat 2 little by little to the upper part through the bottom and into the form 4 solidly by raising a jack 9 gradually. When demolding is performed after the lapse of a retaining period of time for curing of the slurry 5, a composite buiding material 12 through fiber reinforcement is obtained.

Title: Production of hexahydroazepinone and hexahydroazepinol
Inventor: ARUFUREETO ORUPURITSUHI
IPC: C07D267/04
Filed: 1994-12-15
Abstract: The invention describes two industrial processes for the preparation of heterocyclic 7-membered ring ketones by means of Dieckmann condensation with avoidance of the customary dilution method. In addition, the otherwise customary high excesses of base are distinctly reduced and the reaction times are significantly shortened. In one process the 1,8-dicarboxylic acid ester is added to the recirculated reaction mixture in the region of a jet, in the other the 1,8-dicarboxylic acid ester is added to the top of a packed column and diluted along the column by means of the condensate from the reaction mixture boiling under reflux in the column. The yields achieved by these procedures are 80-89% of theory. The distinctly improved yields allow the synthesis of azelastine (INN) and flezelastine (INN) in increased total yield, the final reaction to the end product being carried out in water instead of in organic solvent. Reaction in water gives yields of 70-90% of theory.

Filed: 1995-11-30
Abstract: PROBLEM TO BE SOLVED: To obtain a simple device capable of uniformly spraying spacer particles at a low cost by providing the device with a passage for passing the spacer particles and a shielding member for shielding the passage of the spacer particles by a curvilinear action. SOLUTION: A carrier gas 9 presses the spacer particles 10 downward from between a gap adjusting part 2 and a counter member 5. The spacer particles 10 are sprayed from a nozzle 8 past the passage 11 when the spacers 10 are inserted into the space enclosed by a buckling structure body 1, a spacer 3 for forming the gap and a counter member 5. On the other hand, the buckling structure body 1 is superheated and tends to extend longitudinally when a current is passed to the buckling structural body 1 by impressing voltage on an electrode 6a. A gap adjusting part 2 is, however, fixed and cannot, therefore, extend.  When, thereupon, compressing power P0 exceeds the buckling load, the buckling structural body 1 induces buckling deformation and the central part thereof is deformed to a counter member 5 side, by which the passage 11 is closed and the spraying of the spacer particles 10 from the nozzle 8 is shut off.
